Air Velocity
Air Velocity instruments are portable manometers which indicate pressure and air velocity. Dwyer's air velocity models are accurate instruments designed for measurement of low differential pressures in laboratory and test applications. Ideal for measurement of low range gas and air pressures, positive, negative or differential.

Questions
- Question
- What is the advantage of using a manometer rather than a Magnehelic® gage?
- Answer
- Dwyer Instruments manufactures many different types and styles of manometers with various accuracies and prices for different applications as well as the Magnehelic® gage. For example, some of the many manometers we manufacture are Hook Gage Manometers with ±0.001 inches water column accuracy; Microtector® Portable Electronic Point Gage to ±0.00025 inches water column accuracy; Handheld Digital Manometers with ±0.5 inches water column accuracy; very inexpensive Mark II Molded Plastic Air Filter Gages at ±3% inches water column accuracy. The key point is that we offer many manometers and the selection depends on your specification, application, convenience needs and pocketbook. Some of the key factors to consider that affect manometer performance and usage are: Characteristics of Indicating Fluid, Readability and Leveling. You should read "Measurement of Pressure with the Manometer" in our catalog to fully understand the importance of these factors and their effect on your reading wit
- Question
- What are the principle advantages of red gage fluid over water for use in manometers?
- Answer
- Red gage fluid is slow to evaporate, won't freeze, is more readable and produces slightly expanded scales for better reading resolution.
- Question
- Will the water manometers freeze?
- Answer
- Yes, if the temperature drops below 32 degrees Fahrenheit, the fluid in the manometer will freeze. The fluid used in "W/M" style manometers is water-based with a small amount of fluorescent green fluid to enhance the meniscus. The other gage fluids have a lower freezing point, however, it is recommended that the manometers be stored above 32 degrees Fahrenheit.
- Question
- Is routine maintenance required for a Dwyer red gage fluid type manometer?
- Answer
- Yes. The zero point should be checked periodically as well as the fluid level. After a year of service, particularly with dirty air, the fluid should be replaced to assure that specific gravity changes are not affecting the accuracy of the reading.
- Question
- I have a couple of questions. Does the model 310 manometer require regular calibration and if so, what calibration interval is recommended? Also, if calibration is required, do you have a location which could perform the calibration? Thanks, Richard
- Answer
- The Model 310 manometer does not require any calibration, as long as there has been no physical damage to the gauge. So barring no leaks or cracks, no calibration is needed. We do recommend changing out the gauge fluid every 3 years to ensure proper functionality.
